Hey DOC...
I tried the HP Restore in my 92 S10 Blazer. I've used it with two oil changes. After 570 miles on the second change, the motor now has a tick when you give it gas. After you \drive it for about 25 miles, it goes away until the motor is cool again.
I never really felt any more horse power gain with the stuff. I spoke with my mechanic and he said he's 100% sure the HP Restore caused a sticky lifter.
Any thoughts?? Should I try some of that Lucas oil treatment? That stuff worked wonders for my tranny.
Just curious...
Thanks!!
